If you decrease the Memory controller lower than the HT Link frequency the BIOS will change it back when you reboot. But if you change the "Memory Controller" to 9x (1800) and the second to 1.8... and save it... the northbridge AND the HT Link Speed will be 1800.
Yep... 1st Rule of Phenom. HT Link Spd can't be higher than NB Spd, it's actually a good thing that Bios won't let you do that..

I really hope that stays stable for ya! Running the HT Link at 1800 is not that big a deal, but lowering you NB to 1800 will have a more detrimental effect... If all goes well and you want to get a little more out of it try raising your NB to 10x while leaving the HT@1800.
